This control provides push buttons that issue MCI commands to supported devices. The application should have the MCI device open before the user is allowed to push buttons. When recording audio, open a new file to be sure that the data file is in a format compatible with the system's recording capability. Issue the MCI Save command before closing the device to store the recording in the file.
Note: Non-Common Control properties are prefaced with "mci", suppressed in the following for greater legibility.
